Description: Resistors are a good thing, in fact, they’re actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear into thin air. The only way to be sure that you’re gonna have the resistor you need when you need it is to stock up, and keep them organized. We have just the thing!

Our new branded resistor kit comes with 25 each of 20 different resistor values (including 0Ω links!). All of these resistors are stapled into a tri-fold pack and clearly labeled. The back of the resistor kit even has a resistor color code look-up chart and a table of color codes for the included resistors!

We’d like to give Oomlout credit for coming up with this great idea. Thanks guys!

Values Included:

  • 0Ω, 1.5Ω, 4.7Ω, 10Ω, 47Ω
  • 100Ω, 220Ω, 330Ω, 470Ω, 680Ω
  • 1kΩ, 2.2kΩ, 3.3kΩ, 4.7kΩ, 10kΩ
  • 22kΩ, 47kΩ, 100kΩ, 330kΩ, 1MΩ

Customer Comments

  • I want this, but with capacitors. Please?

    • Double ditto! I just bought the assorted ceramic capacitor bag from RipoffShack, and out of the 100 in the bag, there was not a single one I could use in my project. Plenty of 10pF caps, though.

    • Ditto on the caps!

    • Yes, can we please please please get a capacitor kit?

    • yes, though ceramic or film caps that would be used in exact values in filters, not electrolytics

  • This is long overdue, but very nicely executed. Kudos.

  • “25 each”? Should be a lot more 10 kΩ and 100 kΩ than other values, since you use those a lot more.

  • How stiff are the wires on the resistors? I have bought an assortment in the past that had thin wires that were hard to insert into a breadboard without them bending up.

    • In my experience, ¼ watt resistors tend to have leads similar to 22 AWG wire.

      • I have some ¼ watt with a wire thickness of 0.021" and others with a wire thickness of 0.017. One size goes into a breadboard nicely the others don’t

        • Hi,

          I bought this kit a while back. To answer your question, they are not extremely stiff. For direct PCB/proto board soldering, it is good. For breadboard, I find them too maleable for the task. However, my breadboard is really stiff.


  • It would be awesome to get one of these full of ceramic caps!

  • Quite a nice kit, but I believe the 110R resistor is actually 100 ohms… its actually printed as 110 on the front cover but 100 inside the cover.

  • mentioned the 0 Ohm resistors to my brother in law (masters in EE) says they use them in circuit design on PCBs just in case your calculations are wrong and a specific area might need more resistance. Still I think whats wrong with a wire instead but hey I don’t have a masters in Electrical Engineering.

    • “A zero-ohm link or zero-ohm resistor is a wire link used to connect traces on a printed circuit board that is packaged in the same format as a resistor. This format allows it to be placed on the circuit board using same automated equipment used to place other resistors instead of requiring a separate machine to install a jumper or other wire. Zero-ohm resistors may be packaged like cylindrical resistors, or like surface-mount resistors.”

      from wikipedia… used so that they dont need a different machine for jumpers.

      • Yeah I’ve been thinking about this for a while and having 0 Ohm resistors at your disposal would make PCB design easier. Especially for the layperson whom can probably only manage a 2 sided PCB.

    • it’s identical to a wire, but with the same body as a resistor so it can be grabbed by a machine. there’s no reason to include them in this kit meant for hobbyists. just use a wire.

  • I want a capacitor kit!

  • 0 ohm resistors? I’ve got spools of those and they’ve even got insulation on the outside.

  • When will they be back in stock?

  • Can someone tell me what is the voltage rating (not power) for these resistors? Thanks!

  • Any Chance that you will come out with a ½ Watt resistor kit? For those of us who use bulkier resistors due to… being prone to lighting things on fire…. :/

  • I would pay for a bigger kit if it comes in a great storage unit clearly labeled like your inventors kit.

  • Radio Shack part number 271-312 is a resistor kit with more values. There are more of the more-popular values. It’s pretty rare for Radio Shack to do better than SparkFun, but this is one such case.

  • Great idea but not that useful due to limited selection of values. I’d prefer, say, 10 pcs of 2.5X more values. Or just a bigger kit.

    Also, you need to specify the tolerance.

  • I would rather see a kit with 10 each with 40 different values and or 5 each 80 - 1% would be nice too. AND a good Capasitor kit..like already mentioned.. Thanks, Terry

  • Why 4.7, 47,470, 4.7k and 47k? Why not 5, 50, 500, 5k and 50k? What I need is 60k for a sensor. So that means I have to use a 47k, 1k, 1k, 1k, and a 10k to get there. So it can be done, it just looks unpleasant. Or if I was smarter I could put resistors in parallel. Other site have the multiples of 47 resistors as well. I was wondering what they are used for. Maybe they went in line with a variable resistor for adjustment?

    • l0gikG8 / last year / 1

      Good question. 47 is a standard resistor value. Why is it standard? This site has a good explanation.

      Why not sell a kit with the E24 series instead of the E6? My guess is cost.

      Kits get you in the ballpark while experimenting but if you need something precise, it is better to order the part specifically. Also, ask yourself how precise does it need to be for what you’re doing. With these resistors the value could be off ±5%. In your example, you may not even need a couple of the 1Ks. Or you may need more.

  • Could you tell me where this is made from?

  • OMG these little resistors are carbon, and the values are horrible, I can’t believe my friend wants this as a gift. I’m going to have to show him what good components are; some men have to just keep being taught how to use their equiptment

  • This is a fantastic idea, well executed. So much better than my old system of keep these organized. Thank you Spark Fun!

    • Honey msg me if you want to see the proper workstation and component assortment, this is nothing to write home about

  • What’s the tolerance on these resistors in this pack?

  • SMD version please!

  • Thanks did not see that.

  • When will it be back in stock.

    • For products that are out of stock, SFE tries to give an estimate for new stock on the right hand side of the product page. Currently (2014/01/24) it reads: “We have a purchase for 2000 units. We expect some of these to arrive next on Feb 2, 2014.” I do stress that this is an estimate, however, as logistical issues can always rear their head.

  • What is the pin spacing on these? 100mil, 200mil,300mil,400mil? this is for designing PCBs and need the correct pin spacing for these….Thanks.

  • An irresistible addition to anyone starting out in electronics.

    Color codes in ACTUAL color is a nice touch! I will eventually cut that out and save it when I move my small components and datasheets to a binder (baseball card storer + small baggies).

    I tried putting these resistors in my stiffest breadboard and had with no problem at all! My loosest breadboard holds them pretty good as well.

  • Can we have a PDF of the chart on the back? The sticker is great, but the color version is much more effective.

  • can we get the old unbranded kit back? this kit is way short on values! Also do we really need to pay for 0Ω resistors as part of the kit? I’d call that wire! (unless by some stretch of physics you have found a way for these to really be 0Ω±5% then maybe you could auction them along with your nobel prize!)

  • Is there an SMD version?

  • If only it had some median resistor sizes… Never know when you will need a 12 ohm resistor… Awesome set of resistors for LED noobs to play with…

    • Keep in mind these are 5% tolerance, so if 2 ohms makes a difference in your circuit you should probably be looking for the blue guys…

    • A 1.5 and a 10 in series get you pretty close…

  • Is there any diference between 1/4W and 1/6th Watt PTH at Resistor 330 Ohm 1/6th Watt PTH.

  • I love it!

  • any idea when this is coming back in stock?

    • I have an order with this backordered and was told they’ll have it in stock in the “[n]ext couple of weeks”.

  • Might wanna add “carbon film” and their tolerance to the description, so we don’t have to squint at the picture. ;)

  • Been waiting for something like this! Picked one up.

  • Are these all 5%?

    • Apart from the 0 Ohm resistors, yes. If you look closely at the packaging, you can see the +- 5%. The 0 Ohm resistors are of course +- Infinite % :-)

  • Zero ohm resistors? really? Okay, I can see a use, but I’d really just use a piece of wire, rather than pay for a resistor.

    • Wire looks shoddy. When I open something up from china and see wire jumpers, I am immediately disappointed. But 0Ω resistors look good!

      • I just busted open my old alarm clock and there was wire jumpers all over the place. I have to admit, I was rather disappointed. However I did salvage all kinds of neat parts. I am definitely picking up one of these sweet kits.

        • This kit is on its way to my house along with an Arduino Uno R3 and various other sweet parts. Can’t wait for it to arrive.

  • great stocking stuffer.

    Papa Smurf does bring up a good point. Why 0 ohm? Why not use a piece of wire?

    • Although not really relevant here, they are useful in pick and place, where a wire bridge won’t work properly.

  • Wow really, a Zero ohm resistor?!?! Sometimes I wonder about U guy’s (sniffin too much leaded soldor)

    • I am going to build the world’s highest-precision R2R ladder out of several reels of those 0Ω resistors, once I can find some that are exactly twice their value.

    • They actually are pretty common. They are used in pick and place machines as jumpers- I think wire bridges are harder/require more specialized equipment… :)

    • Actually lead-free solder is much worse for you.

    • The only point I can see in these things is that those who are embarrassed about using jumpers can now make connections without tarnishing their project.

      0 Ohm. Really??

      • It’s linked in the product description; http://en.wikipedia.org/wiki/Zero-ohm_link

        “This format allows it to be placed on the circuit board using same automated equipment used to place other resistors instead of requiring a separate machine to install a jumper or other wire.”

      • 0 Ohm resistors are very commonly used in professional engineering design. They typically have two purposes - 1) you can change the resistor value later if desired. Or, 2) you can use the location as a machine-populated jumper. Then you can save money manufacturing PCBs by designing a board that does several different things, but some features are only enabled if the assembly specifies including that ‘resistor’.

      • We manufacture thousands and thousands of PCB’s where I work, for alot of large international customers and we use 0 ohm resistors and almost every board that we use. They are very common components actually.

Different version of preferred value resistors

Unexpected new values for the breadboard, and hole-through use. These have nice long leads. A version I used to buy was:

30ea. 1K,10K,100K

10ea. 1,10,100,120,150,220,330,470,560,1.5K,2.2k,3.3k,4.7K,15k,22k,47k,220k,470k,1m,10m.

I have been looking for something like this for 10 years

Try getting one form one of the resistor manufactures and you will pay through the nose. Over $100 for a plastic drawer set with the same resistors in this kit. and you have to put them in after you get it.

Love it! I bought two!

Not very conductive

It’s as if the components are resisting my current. I’m not finding them very conductive.

1 of 1 found this helpful:


I keep this next to my soldering iron. I always have the really common resistor values handy now, and don’t have to hunt for them in my supplies stock. This is absolutely definitely assuredly worth the price.

I want one just like this but for ceramic and poly capacitors. Maybe one for molded inductors too.

The only demerit is that these resistors have very thin leads. Too thin to engage most header sockets, and they are hit-and-miss with breadboards also.

One of the best resistor kits out there

I love the way this kit is packaged, its very easy and efficient to find the resistor you need and just snip it out of the tape. Has all of the common resistor sizes and its fairly cheap compared to a lot of kits.

Very useful!

I can never find the exact resistor I need in my messy pile of unlabeled components, and the tiny colored stripes are devilishly difficult to see anyway. So this little booklet of nicely labeled resistors is perfect for my projects!

Resistor Kit

Very useful and convenient. Liked it. Reminds me that I could use some capacitor assortments as well. Bill

There are better products out there.

Although this suffices for a beginner, it quickly becomes a handicap as you learn. There are many kits out there that far surpass this one. This is for a variety of reasons. First of all, out of the 73 standard E12 values up to 1Mohm, only 25 are present. This kit is missing two thirds of the standard values. Second of all, the packaging is extremely lacking. This “kit” consists of little more than resistor sheets loosely stapled to a sheet of thin cardboard. The resistors freely flap around, and it is difficult to access individual resistors. Finally, the leads of the resistors are far, far, far too thin. Even with a breadboard that has fully been broken in, it is difficult to insert these things without bending the leads.

Great Product!

This was exactly what we were looking for to have on hand for any future jobs.


Very nice to have all those resistors all labelled and arranged. A great service you provide. Also your other stuff, and the discussions and teaching. A real plus for us noobies. Please keep up yhr good work and the great support !

Awesome resistor kit

It has all the value resistors nicely arranged and is really handy in use.

Works perfectly

Works perfectly well. No defects. Well packaged and organized. Overall awesome product

I couldn't resist.

A well organized set of assorted resisters. What else is there to say?

Good value

Great value and very handy. Different resistance levels are pretty easy to find, and I like that the body of the resistors are bigger than the ones came with my Arduino kit, so they are less easy to lose sight of.

Great product

The packaging is excellent, keeping all the resistors organized with very clear labeling and resistor code diagrams. Highly recommended resistor kit.

(My only gripe is a pedantic one: the example resistor color code given uses the Latin for “that is” instead of “for example.” Not sure how the editor let that slip…)

Happy with this product!

Great deal!!'

Great kit

Nice selection. The packaging makes it very easy to find what you need.

Just what it says on the tin

Not much to say - it’s a whole bunch of four-band resistors, for all your resisting needs. The packaging is certainly better than bags of parts, or even worse ONE bag with all the parts, but I’ll probably still rehome all the resistors into a plastic divider box.

Best thing I ever owned

Great for breadboard development

I was able to use these parts for my breadboard kits. Its easy to try new resistors to get things right.

Every developer needs this kit!

Need a resistor.. to find just the right timing or drive level…grab the kit. Resistor stoped working because the smoke got out? grab the kit. Spark Fun need a cap kit as well.


Hard to get excited about resistors, but this is a nice selection for my work which is predominantly with small Led projects

Quality Kit of resistors

This kit is exactly as described; LOTS of resistors. I like how it folds out, and It really is nice to know that I have so may resistors to choose from. I have this nagging feeling though that I’m going to run out of a specific resistor one day and be shocked.

lab resistors

Filled my needs for having suitable resistors at hand in my lab. Very good assortment and easy to work with.

Too many of what I don't need

For the project that I’m doing, I don’t need resisters over 100ohm. So there are a LOT of resistors that are going to go to waste - and that bothers me just from the aspect of “I don’t like wasting things”. The price was cheap enough that it’s not a financial issue, so I can’t really complain. It would be nice if packs of lower ohm resistors were available though.

Resistor kit

A real time saver. It’s the perfect kit to have in my parts larder. When I need a resistor for what ever I happen to be working on. I just reach for my stock of resistors, pluck out the one(s) I need and keep working.


They resisted pretty much as advertised and were close to marked values

Do not resist!

I must say the oddest part was the 0 OHM resistors. I have since found several uses ranging from allowing a testing port to op-amp decoupling point. But my favorite is using them to pin things to my cork board. Have a wide range. and a large number of each. A must have for any proto-kit.

good product

Offer more single resistance resistor, such as 330 ohm or 220 ohm, etc.

Hi, We do have specific packs of values such as this 330 ohm pack – https://www.sparkfun.com/products/11507

Its resistors

The packaging is nice as it’s not just a spidery mess of resisters, there is some organization to it. I also haven’t had any duds so far which is also nice. I think the best thing is that you get a decent amount of resistors for very cheap. And since its assorted you should be able to get through most any project with one of these.

Not bad for the price

Overall, good set of resistors. My only frustration is that the ends are very thin and difficult to get into a breadboard with the ends crumpling.

Really handy

Easy to find the resistor i want quickly. The zero ohms is useful when breadboarding and avoids a jumper.

As necessary as a soldering iron

With local suppliers of components becoming rare, this is a required tool. Good selection and they are well labelled.

great kit

I use this kit at my work the variety of resistance values comes in handy. I will be buying more when I need them.

A Mandatory Part of Anyone's Electrical Toolbox

The description for this product is pretty spot on. Many circuits will need resistors and this kit has such a variety, you likely won’t need to worry about whether or not you have the right resistor. The little book they come in is a nice organizer, easy to carry with all resistors neatly sorted and attached on tape rolls. It fit perfectly in my toolbox and I have been the resistor guru among my peers. If you build circuits, or plan to begin building circuits, this product will be as helpful as any breadboard, soldering iron or multimeter. Highly recommended.

Comes very neatly organized and orderly

I’ve ordered large groups of resistors in the past, and they all show up out of order and you have to go through and interpret some chicken scratch they wrote as to what the value was and then hope they sent you all they promised and didn’t forget pr duplicate any. This one comes nice, neat, and organized. Very much worth it.

Great for even the pro, Repeat customer

Sometimes you just need a pack of resistors well organized in a nice book. This saves me tons of time breadboarding a quick circuit. Just flip to the page, pull out the resistor, and go.

I used to have a bucket full of resistors, and it took me a good 10 minutes to find the right value. Multiply that by how many pullups and PWM low pass filters in a given circuit and that is a lot of wasted time. This pack will pay for itself many times over in your time and sanity.

Now if they would only make a book of capacitors…

A Bunch of Resistors

A lot of resistors in a small box. Couldn’t resist purchasing it.

Very Nice Kit

Good selection of values. Nice long leads. Very good price. I’ll no doubt be ordering another in the near future.

good for me

i like it

Wires too flimsy

The resistor gives a handy sampling of resistor values, but I’ve been rather bothered with the thickness of the wires coming out of each resistor. Maybe I’m wrong, but it seems like these wires are flimsier than the ones I’m used to sticking into breadboards. I have to be very careful to apply force in a direction that won’t completely bend the wires as I’m inserting the resistors into a breadboard.

I also don’t have a use for 0 ohm resistors, so I would have prefered getting a different sampling of a large resistance value.

But hey, they do their job as resistors just fine.

Better than expected

I needed a few extra resistors that this kit provided that I didn’t already have laying around. The resistors are all pinned inside this kit and it shows you which ones are which value. All of my other resistors are in a binder and split out into different sections and I loved that. Ever since I got this though, I haven’t used the binder at all. Glad I ended up getting this kit.

A Necessity For Any Project

I got one of these for Christmas and I have no complaints except for the fact that the labels on the inside are out of order and I couldn’t find half of the resistors.

Handy Kit

Good denominations, convenient chart for beginners (and clear colorings)

Saves time when focused on building

When i am organizing components for a circuit its great to have this kit on hand. Dont have to do a BBROYGBVGW each time.

Great buy!

Nice packaging and informative! Great for anyone new to electronics and includes a good selection of the most commonly used resistances.

Just what I needed

Great packaging, convenient access to
